ABSTRACT:
An optical signal emitted from a first optical is applied to a semiconductor laser through a focusing lens so as to propagate through an active layer of the semiconductor laser. In the semiconductor laser, the optical signal is multiplexed with the laser emission power to produce a multiplexed optical signal. The multiplexed optical signal is then applied to a second optical fiber doped with a rare earth element such as erbium to carry out pumping of the rare earth element of the second optical fiber, thereby amplifying the optical signal.
